A few months back, we had a post that declared Trent Richardson to be the second-worst running back of all time, at least by one metric. I clarified that, of course, Richardson is not the worst RB ever -- a new-born baby is less adept than finding running lanes than the Alabama product, for example. And guys who spend their short careers as backups, like Dion Lewis (all due respect to a fellow Pitt Panther) are probably "worse" than T-Rich as well.

But once you agree that Richardson meets a certain threshold -- a featured back, with hundreds of career carries, who still doesn't get the job done -- you'll agree: He's not good. He's arguably the second-worst ever. And Dan "Boom" Herron confirmed that title yesterday by absolutely beasting on limited touches, while Richardson posted another horrendous stat line.

A reminder on who Herron is: Remember when Terrelle Pryor and four other Ohio State players were suspended for five games for selling memoriabilia? Herron was one of those dudes. While Pryor went straight to the NFL, Herron served his suspension and was drafted in the sixth round of the 2012 Draft by the Bengals. He's been a career backup so far, but when Ahmad Bradshaw (and earlier in the year, Donald Brown) went down, Richardson was the only thing standing in the way of Herron claiming a starting gig. So, obviously, he'll be starting next week, because the two backs split carries in Week 13 and Herron went off. The final tally:

The Colts are a juggernaut thanks to their young stud quarterback, a mixture of experienced and explosive receivers, and a rotation of solid, contributing running backs. Richardson is the only blemish on this team's offensive resume. Don't expect him back in Indianapolis next season, first-round-pick-given-up-for-him or not.
